Solvent drying is a key step in many laboratories that are using organic solvents for syntheses and extractions. In the case of hexane extractions during oil and grease measurements, this step is necessary to ensure that the extracts are accurately dried, concentrated and weighed.

If I had to use a single word to describe aquariums, it would be “magical.” Whether you’re a child or a child at heart (like me!), it is easy to get lost with the turtles, sea lions, eels, sharks and any other aquatic life you can imagine. The exhibits closely mimic the sights, sounds and smells of each aquatic environment – so closely, that you might think you’re out in the ocean or in the middle of the Antarctic.
Tuesday Trivia is here again and this week’s question will focus on the EPA and a relatively recent update that applies to semi-volatile organic pollutants in water. If you are ready to Expand Your Horizon, read on.
If you are unfamiliar with terms like “fatberg” and “FOG,” you might not realize the significance and environmental ramifications of this phenomenon. Your perspective will change if you look through recent news articles where fatbergs have blocked and damaged sewer systems in major cities.

I was at a tradeshow the other day and overheard a conversation that stayed with me. The conversation was taking place between two colleagues who were reminiscing about their days in the college chemistry lab.
It’s Tuesday again – ready to Expand Your Horizon? For those who are joining us for the first time, every Tuesday is Trivia Tuesday where we test our wits on various topics. We welcome all reasonable – as well as creative – guesses!
The Tuesday Trivia question for this week:
Imagine shrinking the Earth’s water supply down to 100 liters. The volume of fresh, usable water would be roughly _____(fill in the blank)_____ liters.
Keep an eye out for the answer next Tuesday …
